To check liver destruction and liver synthesis function, choose laboratory liver function; to check liver size and shape, choose liver ultrasound, CT, etc.; to check liver cancer, etc., choose puncture biopsy. As there are many kinds of liver diseases, generally there is no most accurate examination program, just that each program complements each other for comprehensive diagnosis. 1. Liver function: alanine aminotransferase and ghrelin aminotransferase can judge the damage of liver cells; albumin, cholinesterase and transpeptidase can judge the synthesis ability of liver cells; bilirubin can judge the secretion and excretion ability of liver. 2. Liver size and morphology: Liver ultrasound, CT, MRI and other imaging examinations can visually determine the size, morphology and envelope status of the liver. It can also detect cirrhosis, fatty liver, liver cancer and other diseases, as well as determine the size and scope of liver cancer and whether it has metastasized. 3. Puncture biopsy: Puncture biopsy is the gold standard of liver cancer examination. Through histopathological examination, the tissue type of liver cancer can be determined and different treatments can be adopted according to the type. There are also angiography and liver hardness measurement for liver examination, so it is not possible to determine what program is the most accurate. It is recommended that patients should go to regular hospitals for comprehensive examination under the advice of doctors, and adopt treatment plans according to the results of each item.
